Running the latest CVS version of NTop on RedHat Enterprise Server 3
with all current updates applied.
Configured via:
./configure --prefix=/usr/local/ntop --without-ssl
(I'm using Apache to provide the SSL)
I did get a small warning about not finding sctp during compilation, but
none of the nice big boxes...only xmldump not able to be made there (I
can't find any gdome.h downloadable, but no big worry)
Not sure where I'd get sctp from (quick Google didn't show up any
downloadables).
Am trying to run the NetFlow plugin to capture from remote probes, but
whenever I configure an interface for this, it SegFaults.
I checked the lists & see that others have also had this problem, so I
read through the recommended debugging (at the bottom of the excellent
docs/FAQ which misses just 1 gdb command: 'run')
